ABSTRACT:
A device for facilitating location of the printing point and/or the correction of characters comprises a mechanism actuated by a back space key to shift the printing point back. A second mechanism, also actuated by the back space key, moves a pointer to a set position over the printing point simultaneously with the back spacing. A restoring element controlled by a typing mechanism automatically restores the pointer to an inoperative position clear of the printing point before the typing of the selected character. A correcting key, when actuated, sets a suppressor which arrests the movement of a spring actuated actuator to lock the escapement and prearranges a lift mechanism for raising a correcting ribbon into an operative position. A positioner connected to the lift mechanism holds the suppressor in the set position in opposition to the action of a returning spring when the mechanism is prearranged for use and releases the suppressor when the correcting ribbon is raised into the operative position. During its actuation, the actuator replaces the positioner to hold the suppressor in the set position, when the correcting ribbon is in the raised position, and at the end of its actuation, releases the suppressor for its return to the inoperative position through the medium of the return spring.
